1 Unit - "Srivijaya Bean Ingot" Conch, Naga

The Srivijaya polity controlled maritime trade across the Strait of Malacca for several centuries, and its monetary culture reflected that commercial orientation — tin was locally abundant, easily cast, and widely trusted across the trading networks linking Sumatra, the Malay Peninsula, and Java. These small cast ingots circulated alongside foreign gold and silver coinages rather than replacing them, functioning as a fractional medium in port markets where exact weight in metal mattered more than issuing authority.

Attribution to Srivijaya specifically remains contested among scholars, as the political geography of Sumatra between 1000 and 1300 was fluid and overlapping.
